AUTOMATIC-ACTING ALARM-CLOCK SWITCH.

Specification of Letters Patent.

Patented Apiz t, 1922.

Application filed September 7, 1921. Serial No. 499,043.

To all whom it wm c concern 'Be it known that I, VILHELM AUGUST JOHANNES CoRLrN, subject of the Kingdom of Denmark, and residing at Nakskov, Denmark, have invented certain new and useful Improvements in Automatic-Acting Alarm-Clock Switches, of which the follow ing is a specification. I

The present invention relates to an automatic acting alarm clock switch consisting of the combination of an alarm-clock and an electric switch closed by the alarm-movement of the alarm-clock when said alarm-movement is started. The switch may be made to close the current for an electric lamp, heater or the like. I

The apparatus is so constructed, that the switch may be actuated independent of the working of the alarm-clock, thereby that the switch-device may be closed or opened by" 1 denotes the alarm-clock built close to- .gether with an electric lamp-receptacle 2, wherein may be inserted a lamp 3. On the shaft 41' of the movement for the alarm, there is placed an eccentric-wheel 5 around which is provided an eccentric-ring 6. This ring 6 is provided with a pawl 7, which, under the movement of the eccentric-wheel,-may slideon the curved surface of a lever 9, whereas the pawl 7 is pressed against said curved surface with a slight pressure by means of the spring 8. The curved surface of the lever 9 is provided with a projection 14; against which the pawl 7 is forced, when the wheel moves and when the lever 9 is in the positions indicated by full lines. When the'pawl '7 is forced against the projection 14:, the ever 9 is rotated around the tap 12 whereby the lower end of the lever 9 by means of the connecting rod 10 connected to the contact piece 11, closes the circuit by bringing the contact-piece 11 in contact with the station ar contact-piece 11*. g

nder the normal rate of the clock, the parts will be in the position shown by full lines. The alarm-movement isset to operate at a given point of time in the usual manner. As soonas it starts to operate the shaft 4 starts turning and takes along the eccentricwheel 5 whereat the part 7 slides along the curved surface on the lever 9. When the pawl 7 is forced against the projection 14: the lever is turned and the switch closed thereby causing the lamp to be lit simultaneously with the alarm from the alarmclock.

To provide for the lighting and putting out of the lamp independent of the movement of the clock, there is provided a lever 15 by means of which the lever 9 may be actuated. If the alarm movement is stopped in a position in which the pawl 7 blocks the movement of the lever 9, that is, in a position as shown by dotted lines, the lever 9 could not be rotated, if the lever 15 was in fixed connection with the lever 9 and the lamp could not beswitched off. To prevent this drawback the lever 15 is placed rotatable around the tap 13 in the lever 9 and besides connected to an upwardly movable element 16 provided inside the upper part of the lever 9, which is divided in two parts. Said element 16 is normally placed so far downwards that it is not in contact with the pawl 7,'but when the lever 15 if forced downwards, said element is lifted and brings projection 14. The lever 9 may then be rotated and this happens when the lever 15 is forced against the tap 12.

The described device may of course be used in-connection with other apparatus than the lamp shown in the'drawing. The device may for example be used to close the current to an electric heater at a given point of time. Besides it may be used to light the lanters inan automobile in that manner, that the alarm-clock is'set to operate at the enjoined time of lighting. In such cases the alarm-clock will of course not be provided with a bell. I

I claim:

1. In the combination including an electric lamp and an alarm clockwork, switch mechanism for the lamp circuit comprising a disk eccentrically mounted on the shaft of the alarm mechanism, a ring on the disk carrying a pawl, a double-armed lever rotata ly mounted on a fixed tap and having a curved upper surface with a projection at one end, a fixed contact, a movable contact, a connecting rod between the end of the lever thereby the part 7 out of contact with the v opposite the curved surface and the movable contact, a. spring normally urging the pawl in contact with said projection on the curved surface, so that the shaft of the alarm mechanism rotates, the lever is rotated to force the movable contact against the fixetl contact, and a second lever for operating the first lever independent of the alarm mechanism.

2. A. switch mechanism as described in claim 1 wherein the first lever is made in two parts with a movable element slidable therebetween and the second lever is rotatable about a projection on the first lever so that when the pawl assumes a position in which it locks the movement oi the first lever, the second lover is first rotated about the projection on the first lever to lift the movable element and raise the pawl out oil coutart from the projection on the curved surface and thereafter the sccontl lever on its 'l'urthcr movement carries along the first lever.

In testimony whereof I iallix my signature.
